超低容量喷雾技术

超低容量喷雾 Ultra-low volume spraying

  超低容量喷雾是农药使用技术的新发展,既可广泛应用于农作物和果林、花木的病虫害防治,又可用于温室大棚的消毒。它是利用一种特殊设备,如飞机或地面超低量喷雾器喷洒,使药剂的雾点达到80至120微米或更细,由于雾滴直径极小,喷洒省工省时,又不需用水,尤其适用于山地和缺水少水地区。

  山东兆源智能科技有限公司生产的多旋翼植保无人机,可搭载高压雾化喷头或者静电离心喷头,是超低量喷雾的专用器械。它对药剂不需要特殊加工处理,只要在原药(原油)中加入极少量的溶剂,以解决因药剂粘滞性过大而影响喷雾质量。

  使用超低容量喷雾的主要特点有:
  一是工效高。喷雾速度每秒钟可达到5至8米,这对防治暴发性的病虫害十分有利。不仅可以用来防病治虫,也可喷施除草剂防除杂草,尤其适合施用灭生性的除草剂,如垦殖荒地、公路铁道两旁、林地和果园苗圃的行间除草。
  二是用药量少。每亩一般用几十毫升至几百毫升的药液,就能均匀地喷到一亩地上的农林作物。
  三是原药液一般不需要加工,就能直接使用,这对节省溶剂、乳化剂、填充剂、包装材料等都是很有利的,从而可大大节约成本。
  四是浓度高、药效长,药剂的有效成分可达80%以上,因此残效期相应延长,防治适期也可适当宽些。
  五是作物附着的药物接近原药,其挥发性浓度高、熏杀作用大,药剂接触到害虫与病菌时,能很快地向害虫、病原体内侵入或渗透,能大大提高防治效果。
  六是喷药时药剂因雾点很细,粘附在作物上的比例相应大些,因此,流失量减少,对环境、大气、河流的污染也大大减轻。

  在进行超低容量喷雾,尤其是直接喷施不加水的油剂农药时,由于农药含量高,浓度大,必须采取防护措施。
  操作人员一定要穿工作服、戴口罩和风镜、手套及帽子,作业时不准吸烟或吃东西,作业完毕要立即洗净手脸,工作服要勤洗常换。

  无人机应用超低容量喷雾技术可扬长避短,离农作物2-3米高度透过旋翼高速旋转所产生的相当于四至五级风的下行气流实施精准施药。
  注意处理好几个关系:
  1.旋翼单方向旋转所产生的扭力区对药雾的卷扬对设备的污染和侵蚀。
  2.在狭窄区域与高温天气处理好设备作业高度、飞行速度作业宽幅与下行力的关系最大化规避药雾的拖行、漂移、弥漫和蒸发。
  3.计算好宽幅、飞速、高度和药量。做好按要求均匀施药规避药液过量造成药害和药量不足造成灭虫效果不好。
  4.注意有机硅对设备的损害做好充分的防范。

ULTRA-LOW VOLUME SPRAYING

 These concentrates may approach 100 percent active ingredient.
 They are designed to be used “as is” or to be diluted with only small quantities of a specified carrier.
 They are used at rates of no more than 1/2 gallon per acre.
 These special purpose formulations are used mostly in outdoor applications, such as in agricultural, forestry, ornamental, and mosquito control programs.

 Advantages of ultra-low-volume formulations include:
 Relatively easy to transport and store
 Remain in solution; little agitation required
 Not abrasive to equipment
 Will not plug screens and nozzles
 Leave little visible residue on treated surfaces

 The use of ultra-low volume pesticide spraying operation can limit the cost of water and pesticides. Moreover, using remote control allows the operator to stay away from chemical pollution, it’s greatly reducing the harm to the operator.

 It is designed and manufactured by Joyance Tech with complete patents protection.
 It does not require a runway to takeoff or landing, it takes off vertically. Intelligent Auto pilot system has been installed, which effectively lowers the operation difficulty and the risks.
 Flying at low altitude of several meters, the dusting effect can be controlled in the sight-distance range.
 It is suitable for all kinds of complex terrain farmlands and the crops and woods of different heights. Accurate dusting can be achieved for different crops in the adjacent farmlands.
 Due to intelligent Auto pilot system installed, the dusting operation can be mastered via simple training.

 The dosage of pesticide is reduced, so it can minimize the pollution of pesticide to the environment and crops.
 It is not harmful to the operator in the distances when dusting, and the labor intensity is reduced dramatically.
